2 Claims. (01. ita -1'16) This invention relates to an attachment for looms, the important object of the invention being to provide automatically controlled means for lifting the fillings of the idle shuttles of a loom, out of the path of travel of the active shuttle, during the weaving operation, thereby eliminating what is commonly known as jerked in filling, which results in a defective weave and an inferior grade of material produced.

Another object of the invention is to provide a device of this character which may be readily and easily mounted on the usual loom structure, and operated by the shuttle box motion of the loom, eliminating the necessity of installing expensive machinery and making changes in the loom structure, to mount the attachment.

With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure 1 is a, perspective view of the attachment illustrating its relation with respect to the breast beam of the loom.

Figure 2 is an end elevational view of the loom equipped with an attachment constructed in accordance with the invention.

Figure 3 is a front elevational view of a loom equipped with the attachment.

Figure 4 is a plan view of the attachment, the lifting rods, being shown in section.

Figure 5 is a sectional view taken on line 5-5 of Fig. 4.

Figure 6 is a fragmental view illustrating a strip of cloth wherein the filling of an idle shuttle has been jerked into the weave at the selvage.

Referring to the drawings in detail, the reference character 5 designates the frame of a loom equipped with the attachment, forming the subject matter of the present invention.

The reference character 6 designates the breast beam of the loom, to which the lifting wires 1 of the attachment, are connected, there being provided coiled springs 8 connecting the wires to the breast beam, as clearly shown by Fig. 1 of the drawings.

The reference character 9 designates the shuttle box support, that is operated in the well known manner, as by means of the shuttle box motion, which includes the shaft 10 supported on the frame of the loom, by means of the brackets H and 12.

On one end of the shaft [0, is a segmental gear l3 that meshes with the gear l4 that in turn is secured to the shaft on which the cams l5 are mounted to rotate therewith. These cams are arranged with respect to each other, so that the bars l6, to be hereinafter more fully described,

will be moved various distances to raise and lower the lifting wires of the attachment.

The shaft on which the cams [5 are mounted, is indicated by the reference character It, and is mounted in the bracket I! that is secured to the cross-beam [8 of the frame of the loom.

The bars 16 are pivotally mounted on the shaft l9 and are of lengths to extend to points intermediate the front and rear edges of the frame of the loom. These bars l6 have connection with the vertical rods 2!] through the turnbuckles 2 l so that the rods 20 may be accurately adjusted with respect to the bars [6 to vary the throw of the rods, and consequently regulate the movements of the lifting wires 1, which are connected to the rods, as shown by Fig. 1.

The rods 20 operate through bearings formed in the arm 22 which is secured to the frame of the loom, the bearings acting to maintain the rods vertical at all times to insure the true operation of the attachment.

The operation of the device is substantially as follows: When the shuttle boxes which are indicated at A are moved, by the shuttle box motion, the shaft l0 rotates to raise or lower the shuttle boxes, to bring a particular shuttle in line with the race plate of the loom.

With this movement of the shuttle box supporting rod, the cams l5 are operated which in turn engage the bars 16, elevating the bars which in turn elevate the lifting wires 1, over which the fillings from the idle shuttles rest. As the wires 1 are elevated, it is obvious that the fillings from the idle shuttles will also be elevated out of the path of travel of the active shuttle which is put in motion in the usual and well known manner.

From the foregoing it will be seen that due to the construction shown and described, the active shuttle will operate free of the fillings of the idle shuttles to the end that it would be impossible to jerk in the filling of an idle shuttle, to render the weave inferior.

What is claimed is:

1. In a device of the character described, the combination of a loom having a plurality of vertical movable shuttle boxes and shuttle operating means for operating said shuttle boxes, said operating means including a rotary shaft, a cam shaft mounted on the loom, a plurality of cams on said cam shaft, a gear on one end of the cam shaft, a segmental gear on the first mentioned shaft and being in mesh with the gear on the cam shaft and adapted to operate the cam shaft, pivoted lifting bars mounted on the frame of the loom and resting on said cams, vertically movable rods, adjustable connecting means connecting. the lifting bars and vertically movable rods, liftthe frame'of the loom, said lifting wires adapted ing wires connected with the vertical rods, yieldable members connecting said wireswith the loom 7 v frame, said wires being extended across the inner end of the shuttle boxes, and providing lifts for the fillings from the shuttles, and said lifting wires adapted to elevate the fillings of idleshuttles above the path of travel of the active shuttle,

during the weaving of cloth.

2. In a device of the character described, the combination of a multi-shuttle loom and the shuttle boxes thereof, means for operating said shuttle boxes, said operating means including a rotary shaft, a cam shaft operated by said rotary shaft, a plurality of cams mounted on the cam shaft to move therewith, a plurality. of vertical movable rods, bearings mounted on the loom and through which rods operate, normally horizontal wires being connected with the rods, coiled springs connected with said wires and being secured to to move under the fillings from the shuttles, and

said wires adapted to engage the fillings from idle shuttles, elevating'the idle shuttle fillings above the path of travel of the active shuttles during the weaving of cloth.'
